Title: Active suspension device for vehicle
Inventor: KISHIMOTO HISAHIRO
IPC: B60G23/00
Filed: 1990-08-20
Abstract: PURPOSE:To most suitably carry out hydraulic control to an impulsive vibration by carrying out hydraulic control in proportion to the spring vertical acceleration in a frequency band larger than a resonance frequency, in responsive to the vertical acceleration of a vehicle body in the vicinity of the spring vertical resonance frequency, when a vibration-input detecting means has detected a vibration-input object. CONSTITUTION:A controller 30 always monitors the signal values of a preview sensor 35, and reads the output signal values of the detected ultrasonic reflected waves, and judges whether or not there is the output of a preview control signal that denotes the detection of a vibration input object such as a projection, and when the result of the judgment is YES, the switch circuit denoted by 30S is closed. And, by an adding circuit 30g, the hydraulic control quantity obtained by a phase-advance compensating circuit 30f is added to the hydraulic control quantity at the time of normal traveling to determine the hydraulic control quantity for controlling a control valve 17. On the basis of this, the controller 30 changes the driving signal for operating the control valve 17, and changes the supply/discharge of hydraulic pressure in the direction in which the hydraulic pressure to be applied to the hydraulic chamber of a hydraulic actuator is decreased.

Title: Semiconductor laser
Inventor: KUME MASAHIRO
IPC: H01S5/00
Filed: 1984-10-19
Abstract: PURPOSE:To enable to significantly reduce the mode hopping noise of a laser beam, which is generated by a return light, by a method wherein the concentration of Te, which is used as an impurity to be added to the clad layer on the N side, is set at the specific value or less. CONSTITUTION:The laser beam, which is made to oscillate by stimulated emission in an active layer 3, generally oozes out in clad layers 2 and 4 on both side thereof, and moreover, the Te being used as a dopant for the clad layer 2 on the N side is known to form supersaturated absorbers and the laser beam is subjected to the effect of the supersaturated absorbers. Accordingly, the single mode property of this laser comes to being made to improve by the supersaturated absorption effect of the Te. As the concentration of Te is made to reduce, the single mode of the laser is turned into a multimode, whereby the amount of return light is made to change so as to make noise reduce. When the concentration of Te is 1X10<18>cm<-3> or less and the amount of return light is 0.05% or more, the mode hopping noise of the laser beam can be sufficiently reduced, in particular, when the concentration of Te is made lower into 1X10<17>cm<-3> or less, a very low-noise element can be realized.
